Let's take it one step at a time, starting with what I think should be common ground.  Two hypotheticals:

Scenario #1

You can choose between two players:

Player A:  His value is rated at 90.0.  However, he plays at a position where the team already had a 95.  As such, he's likely to be sitting the bench as a backup unless an injury happens.

Player B:  His value is also rated at 90.0.  However, he plays at a position where we have a 47.  As such, he's likely to start every game.

Are we all in agreement that Player B would help us win more games?  

Scenario #2:

You can choose between two players:

Player X:  His value is rated at 90.0.  He plays at a position where the team already has 88.  As such, he'll start, but would only be a very minimal upgrade over a player already on the team.

Player Y:  His value is also rated at 90.0.  However, he plays at a position where we have a 47.  As such, he'll start, and would be a huge upgrade over our other alternative at the position.

Are we all in agreement that Player Y would help us win more games?
